A control apparatus for a vehicle, which is provided with an engine and drive wheels, is configured, during an inertia running or stop of the vehicle, to execute a control for stopping the engine and/or disconnecting the engine from the drive wheels in each area, depending on whether a condition is satisfied or not. The condition is set based on an information transferred from other vehicle in which the control is executable during an inertia running or stop of the other vehicle. The information includes (a) a location information indicative of the each area and (b) an acceleration representative value representing a required acceleration of the other vehicle required by an operator of the other vehicle in the each area. The acceleration representative value is associated with the location information indicative of the each area.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A control apparatus for a vehicle provided with an engine and a plurality of drive wheels to which a drive force of the engine is to be transmitted, the control apparatus comprising: a processor programmed to: during an inertia running of the vehicle, execute a control configured to stop the engine or disconnect the engine from the plurality of drive wheels when the vehicle is (a) in a location of one specified road area of a plurality of road areas in which fuel efficient driving is performed to limit acceleration of each vehicle of a plurality of other vehicles, and (b) a value of a required acceleration of the plurality of other vehicles in each of the plurality of road areas is less than a predetermined acceleration value, which is set based on a level of the road or an intersection of the road, the location of each of the plurality of road areas and the required acceleration of the plurality of other vehicles at the plurality of road areas being acquired from the plurality of other vehicles; and during the inertia running or the stop of the vehicle, prohibit execution of the control configured to stop the engine or disconnect the engine from the plurality of drive wheels in response to failing to satisfy the predetermined condition when the vehicle is located in the one of the plurality of road areas.
2. The control apparatus according to claim 1 , wherein the processor is programmed to: determine whether executing the control, depending on a difference between the acceleration representative value representing the required acceleration in the plurality of other vehicles when the control has been executed in the plurality of other vehicles and the acceleration representative value representing the required acceleration in the plurality of other vehicles when the control has not been executed in the plurality of other vehicles, and not execute the control in one road area of the plurality of road areas indicated by the location information that is associated with the acceleration representative value, in a case where the difference is larger than a threshold value.
3. The control apparatus according to claim 2 , wherein the processor is programmed to: determine which one of a drive force performance and a fuel efficiency performance of the vehicle is given more importance by the operator of the vehicle, and execute the control in the one area indicated by the location information that is associated with the acceleration representative value, irrespective of whether the drive force performance and the fuel efficiency performance is given more importance by the operator, in a case where the difference is not larger than the threshold value.
4. The control apparatus according to claim 2 , wherein the threshold value varies depending on which area of the plurality of areas is indicated by the location information that is associated with the acceleration representative value.
5. The control apparatus according to claim 1 , wherein, in a case where the acceleration representative value associated with the location information indicative of one area of the plurality of areas is larger than a threshold value, the processor of the control apparatus does not execute the control in the one area of the plurality of areas.
6. The control apparatus according to claim 5 , wherein the processor is programmed to: determine which one of a drive force performance and a fuel efficiency performance of the vehicle is given more importance by the operator of the vehicle, and execute the control in the one area of the plurality of areas that is indicated by the location information that is associated with the acceleration representative value, irrespective of whether the drive force performance and the fuel efficiency performance is given more importance by the operator, in a case where the acceleration representative value is not larger than the threshold value.
7. The control apparatus according to claim 5 , wherein the threshold value varies depending on which area of the plurality of areas is indicated by the location information that is associated with the acceleration representative value.
8. The control apparatus according to claim 1 , wherein the processor is programmed to execute the control in a case where an actual fuel efficiency is reduced by at least a threshold ratio when the control has not been executed.
9. The control apparatus according to claim 1 , wherein the processor is programmed to: generate the location information indicative of one area of the plurality of areas and the acceleration representative value representing the required acceleration of the vehicle required by the operator of the vehicle in the one area, the acceleration representative value being associated with the location information indicative of the one area, and transfer the generated information to an external device that is located outside the vehicle, via a transceiver provided in the vehicle.
